Load balancing cluster system and method for providing services using it

Abstract

The invention provides a load balancing clustered system and a method for providing services by using the load balancing clustered system. The load balancing clustered system comprises an upper link switch which is connected with client sides and connected with a plurality of load balancing devices, the upper link switch is provided with a routing table to receive request messages sent by the client sides, and selects a load balancing device to send the request messages according to the routing table and the request messages. The load balancing devices are all connected with the upper link switch, receive the request messages, select a rear end server according to preset load balancing strategies for the request messages, and replace a destination address of the request messages with an address of the rear end server. According to the load balancing clustered system and the method for providing services by using the load balancing clustered system, flows carried by each load balancing device are relatively even, load balancing capacity is improved, visiting speed of the client sides (internet) is increased, utilization rate of each rear end server is increased, the phenomenon that virtual services wait for process in some rear end servers is avoided, and processing speed of the virtual services (request messages) is increased.

Description

technical field [0001] The invention relates to the technical field of computer networks, and particularly designs a load balancing cluster system, a method for providing services using the same, an uplink switch and load balancing equipment. Background technique [0002] The load balancing device (LB) provides a general load balancing method for various business applications. However, all business data packets need to pass through the load balancing device. The single-machine data packet processing performance of the existing load balancing device is low, and the business flow that needs to be processed by the load balancing device is much higher than the single-machine processing capability of the load balancing device. Therefore, the stand-alone load balancing system can no longer meet this demand. [0003] Use the Virtual Router Redundancy Protocol (VRRP) to expand multiple mutually active and standby load balancing devices. This method uses the VRRP protocol to expand...

AI Technical Summary

Problems solved by technology

When the traffic of a certain virtual service is too large, this method will not be able to deal with it

[0006] (2) The VRRP protocol is a two-layer protocol, requiring each load balancer to be in the same two-layer, and most of the current network design is three-layer, using VRRP will cause troubles in network deployment

[0007] (3) When using this method, since the master device and slave device of different services are different, the specific configuration of each load balancing device will be different, which is inconvenient to use
